RELOCATING MACHINE CODE PROGRAMS
IN THE TS-2068
By James F. Brezina

Why would one want to relocate machine code? Many machine
code programs written for the 2068 are located in the sane area
of RAM. Sometimes one might want to use both if they can be
used that way. If you relocate one, you may be able to use
both. I had previously purchased the Zeal dissassembler and

2

found that I couldn't use my printer driver with it becau
they both used the same area of RAM to store their nachine
code. Although the printer interface I used (TASMAN) had a
driver program to store in the computer's printer buffer, 1
found that I couldn't use that either because something in the
Zeal dissassembler would wipe that out. I found out that, even
after transferring the printer driver to an address below the
Zeal dissassembler machine code, I still could not use it
directly through the Zeal dissassembler. I had to use the
Tasman screen copy routine to get a printout of the screen.
Tasman has 2 screen copy routines. One is for text only and is
Stored with the regular printer driver. The other is stored in
the computer's printer buffer and will copy anything on the
screen. The computer's printer buffer location is reverted to
normal with NEW.

Machine code prograns that have been saved on tape or disk
are loaded back into the computer memory with LOAD "CODE (or
a name can be specified (must be for some disk sytens)). With
that simple way of entering, the code is placed at the sane
address it was saved from. If you want to relocate it, then you
enter LOAD "*CODE (address) and it will load in at. the address
specified. If the code contains only relative jumps and ROM
calls, it can be run with no changes. If it contains- absolute
jumps and calls within its own addresses, these vill have to be
changed for the program to work. I have succesfully done this
to a few programs and got them to work.

A dissassembler program comes in quite handily fo,
accomplishing the changes. I use the ZEAL dissassembler since
it prints out the addresses in decimal. The ZEAL dissassembler
has a set up to print to a printer, but, as far as I can tell,
it only supports the 2040 printer. The Zeal dissasembler did
give me an option to have the program dissasseabled in its
present location and in its original location, or at any
address I choose. If you want, you can get printouts at both
locations. In order to get a printout of the Zeal disassenbly,
it was necessary to break out of the Zeal program with CAPS
SHIFT/BREAKand then copy the screen. This was a little tough to
do on the first break out, but, after that it was no trouble.

If you have made the printouts at both locations, take the
two printouts and compare them. One of the things you will
Notice is that the relative jump addresses are different. This
is correct and they do not have to be changed. You will then
notice that the absolute jumps and calls are the same in both
listings. You will also notice that paired registers are loaded
with numbers. These numbers are equivalent to addresses in the
code. Generally, these are the HL register. All the absolute
jumps will have to be changed. If the calls and HL numbers are
to ROM or (in most cases) to addresses below 26710, they do not
Need to be changed. If the calls and HL numbers are to
addresses in the program, they will have to be changed. what I
do, in this case is look for the address shown in the original
program. Then I find the comparable address in the relocated
program and break it down into High Byte and Low Byte (i.e.
(continued on page 3)

RELOCATING MACHINE CODE PROGRAMS
IN THE TS-2068
continued from page 2

High Byte = INT(address/256) and Low Byte = address - High Byte
2 256). Once you have this information you go back to the
relocated address that originally listed that address in the
Anemonics and POKE the following two addresses vith the low
byte and high byte in that order.

It is a lot of work, but, once you have everything changed,
you have a relocated program that works like the original. You
aust resave the changed program and it will load back in at the
new address without specifying the new address. Remember that
you must set RAMTOP at one address below the start of the code.
Since I now have the Tasman printer driver located at 60000 and
the Zeal dissassembler loaded in, 1 initialize the printer
driver with RANDOMIZE USR 60003, and then use RANDOMIZE USR
50000 to make a text only screen copy.

I have used this procedure to nove other programs. One of
then was the screen copy code that Tasman had supplied. Tasran
had listed a number of printers for Copy codes they had on the
cassette, but, they didn't list ay printer (Panasonic) by name.
I tried all of them, but, the only one that appeared to work
correctly was one called Shin-Wa. These screen copy codes vere
ali stored in the computer's printer buffer. There is one thing
wrong with the code being located in the computer's printer

ffer. When you key NEW, the code is erased. I loaded in the
eal, followed by the relocated printer driver, and then the
screen copy code. I got a printed copy of the dissassembly of
the screen copy code. I wanted to relocate to 63000, but since
that was in the Zeal code area | chose 53000 to locate it at
temporarily and then set the relocation to 63000 (10000 bytes)
in the printout. Using the 53000 made it siapler to figure
start addresses. | then made a hard copy of the disassembly and
went back to the menu and changed the relocation to zero and
nade a hard copy of the code at 53000. Comparing all three
listings, I found where I had to make the changes.

After entering the changes at 53000 to 53256, I saved the
code. Then, turning off the computer to clear everything out,
I turned the computer on again, set RAMTOP at 62999, LOADed the
copy code in at 63000. I then resaved the program at the proper
address. I now have a screen copy code that remains in nenory
after NEW.

I think I should aention here that, one of the addresses
loaded into the HL register in the screen Copy program is used
to contain a number which is used to control the size of the
screen copy. That address wili containa | for small screen
copy and 9 for large screen copy. The large screen copy will
not copy the full horizontal screen. It will bea few columns
short on the right side. This is an example of the reason for
changing the numbers held in the HL register.

Although, I do not understand enough to write ay own machine

2, I understand enough to figure out how to do things like

relocating machine code. If you understand enough to figure
that out, you can do it too.

TIMEK TIDBITS

The Nite-Tines News has been providing the vrong dates for
the Timex Sinclair Sunstate Winterfest. The correct dates are
4-6 March 1987.

Ron Havlen (Editor of the Zebra FOD Newsletter) has adapted
two CP/M telecomaunications terminal programs to the Zebra FDO
system (CP/M mode only). This allows the Zebra FOO users to
download and use public domain CP/M software with their
systems! For a copy of the two terminal programs (Modem and
Moden=7) send a blank 3 inch disk and return postage to: Ron
Havlen, 43307 Chambers Road, Horseheads, NY 14845. Ron also has
a disk of additional public domain CP/M software that you get
by sending a second disk to hia.

The LISTing Newsletter reports that ALJ Assembly will no
longer be supplying microdrives or cartridges. They had
approximately 89 left. For more info, write or call Aas
Assembly at 2842 Aiello Drive, Suite C, San Jose, CA 95111,
tel: 408/281-0100.

The LISTing also reports that Richard Moldovan (7414 East
Cuernavaca Place, Tucson, AZ 85710) has been selling voice
synthesizers for $39.00! These work via an RS-232 port (like on
the QL).

The Pixel Print Press Newsletter is available as a service

to the owners of Pixel Print. To get a one year subscriptior
send 4 business sized SASE to Lemke Software Developement, 2145

The Capital Area Tinex/Sinclair Users Group (CATS) is
exploring the possibility of hosting a Timex/Sinclair
conputerfest during the second weekend of May (13-14) 1989.

CATS Newsletter reports that Anstrad has released the
Spectrum 12843 for approximately 299 pounds. It uses a three
inch drive and is NOT COXMPATIBLE with virtually any Spectrum
peripheral on the market. It has a different expansion port
pin-out and it doesn’t allow paging. It has new, improved
joystick port that is not Kempston or Sinclair compatible!

Herb Bowers (2588 Woodshire Circle, Chesapeake, VA- 23323)
has The New Tax Law And You, and Form W-4 programs available
for $7.00 each or $12.00 for both. These come on cassette only
for the TS-2068.

The Greater Cleveland Sinclair Users Group is still
exploring the possibility of hosting a midwest Tinex Sinclair
computerfest. If they do, it will be in later 1988 or early
1989.
